*** TODAY'S PUZZLE ***
More laptop fun tonight as Simon calls in from holidays with a fascinating new puzzle from Leonhard Kohl-Lörting called Cornered Colours. It involves a tiny twist on Yin-Yang logic but the result is captivating. A beautiful sudoku with a gorgeous flow.

Play the puzzle at the link below:
https://sudokupad.app/bmh85ce33k

Rules:
Normal sudoku rules apply. Shade some cells such that all shaded cells form an orthogonally connected area, all unshaded cells form an orthogonally connected area and no 2x2 area is entirely shaded or unshaded. Digits in cages may not repeat and sum to the given clue. In cages, shaded digits count as positive numbers, and unshaded digits count as negative numbers.

Thanks to all of you who have helped us achieve the milestone of 600,000 subscribers on YouTube. Below you can find a link to a free puzzle pack we have curated to celebrate :)
